sooner FOR CURTAIN rasrnnnns.

HHSSUED Application filed January 16, 1924. Serial No. 686,586.

To all 207mm it may concern.

Be it known that I, JOHN VoDIoKA, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Sockets for CurtainFasteners, of which the following is a specilication.

My invention is more particularly concerned with automobile curtains butit will be obvious from the following specification that it may also beemployed in various other constructions. In the constructions to whichmy invention relates the curtains are provided with a convenient ordesired number of posts and the framework about the openings to beclosed with corresponding sockets to receive the posts which areprovided with socket-engaging members to interlock therewith. It isdesirable for obvious reasons that the socket members project as littleas possible beyond the surface of the frame and otherwise be asunobtrusive as possible. My improved socket meets this requirementpresenting a neat inconspicuous appearance when the curtain is off, andis then automatically closed against the entrance of matter which mightclog it and prevent the entrance of the post.

In the drawing accompanying and forming a part of this specificationFigure 1 is a central section of a preferred embodiment of my inventionpartly in elevation; Fig. 2 a side elevation thereof; Fig. 3 a face orplan view; Fig. 4 a bottom plan; Fig. a face plan of the main socketmember or cup; Fig. 6 a section on the line G6 of Fig. and Fig. 7 asection of another element of the device. I

It has not been thought necessary to show the post member of thefastener, a variety of such suitable for use with my improved socketbeing known in the patented artand on the market.

The socket comprises a cup member 8, an attaching screw 9, an. annularcatch or flange member 10, a closure plate 11 and a spring 12.

The cup 'member is struck up out of sheetmetal of suitable strength intothe shape :shown in Figs. 5 and 6 and comprising a cylindrical barrel 13with an outwardly turned octagonal flange 1 1- at one end there of, theother end of the cup being somewhat reduced and of hexagonal or otherangular cross section as at 15. The bottom of the cup is centrallyperforated at 16 for the reception of the shank of the screw 9. The headof the screw is hexagonal or of other shape to fit the reduced bottomportion of the cup. In assembling the socket the screw is dropped intoplace and the cup pinched in over the head thereof as shown at 17,Fig. 1. i

The flange or catch member is struck up in the form shown in Fig. 7 withthe inwardly sloping funnel-shaped portion 18 terminating in stiffeningflange 19 and the outer octagonal flange 20.

In assembling the socket, after the screw has been secured in position,the spring 12 is inserted, the closure plate 11 put in position with theflange 21 inturned, then the annular catch member is placed over flange14; and flange turned under the latter. The socket is then complete,ready for use.

In applying the socket to a wooden frame member a hole is sunk in thelatter to receive and closely fit the cup and preferably a hole isdrilled to receive the screw.

The socket is then driven home by the application of a wrench to theoctagonal flange thereof. In use the closure yields to the post when thelatter is inserted and the post is formed or provided with expanding orlaterally projecting engaging or hook members which engage the catchflange on the cup. When the post is unlatched the closure plate assistsin expelling it and closes the mouth of the cup.

I claim:

1. A socket for curtain fasteners of the class described comprising acup having an outer flange at its mouth angular in outline. an annularmember of similar angular peripher I fitting over and embracing theflange and having an inwardly 'u'ojecting lip, thev cup being formedadjacent its bottom with a portion angular in transverse section. ascrew the shank of which projects axially through the bottom of the cup,the head of the screw being angular in outline to fit closely within theangular bottom portion of the cup, a plate closing against the lip ofsaid angular member and a spring interposed between theplate and thebottom of the cup.

2. A socket for curtain fasteners of the class described comprising acup the peripheral wall of which adjacent the bottom is angular intransverse section, a screw having an angular head of similar shapefitting closely within the angular portion of the cup, the shank of thescrew projecting axially through the bottom thereof, the wall of the cupbeingrpinched in above the head of the screw, said-cup being formed withan outwardly extending flange of angular out- 10 line, an annular memberof similar external periphery embracing the'flange on the cup and havinga lip projecting slightly into the cup, a closure plate normally seatingagainst said lip and a spring intermediate the 010- 15 sure plate andthe bottom of the cup.

JOHN VODICKA.
